GRAPPLE FOR EAY-LOADERS.

Specification of Letters Patent.

Patented Nov. 6, 191 '7 Application filed. July 31, 1916. Serial No.112,295.

To all whom it may concern:

Be it known that I, TAMESABU'RO AnAKI, a citizen of Japan, and aresident of Fromberg, in the county of Carbon and State of Montana, haveinvented a new and Improved Grapple for Hay-Loaders, of whleh thefollowing is a full, clear, and exact description.

My invention relates to a portable apparatus for loading hay or thelike, and is more particularly intended for use in loading material froma stack onto a vehicle.

Reference is to be had to the accompanying drawings forming a part ofthis specification in which similar reference characters indicatecorresponding parts in all the views.

F igure 1 is a plan view of my improved grapple, some of the controllingcables and portions of others being omitted;

Fig. 2 is a side elevation of the grapple.

My improved grapple is adapted to be suspended from any overhead boom orother support. The grapple is equipped with a series of grabs, 19, 19said grabs being alternately shorter and longer so that they may beclustered in compact form. Each grab has a tine, or tines, 20, and thegrabs are pivoted as at 21, 21 for radial swinging movement to close andopen the grapple when grabbing and depositing a load. The pivots are inbrackets, 22, 28, on thegrapple frame 18. The grapple is suspended froma hoisting cable 24 from which branches 25 run to the upper ends of thegrabs 19, 19*. In order to swing the grabs outwardly on their pivots foropening the grapple, a cable 26 connects with a ring 27, from whichbranch cables 28 run over sheaves 29 on the heels 30 of the grabs, theends of the cables being fast to the frame of the grapple as at 31.

The cable 26 controlling the grabs, 19, 19 runs in practice to anysuitable operating means (not shown).

In the use of the grapple, as for example in taking hay or straw from astack, the grapple is raised to the desired height through the medium ofthe cable 24 and positioned over the stack. The grapple is then loweredby the operator onto the stack and the cables 24, 26, are so manipulatedas to open the grabs and close the same on a load, whereupon the grappleis raised and moved by any suitable carrying means (not shown) over awagon to be loaded, for example. When the grapple is over the point ofdeposit of the load, the cable 26 is manipulated to release the grabsand permit the load to drop.

By the described construction, one man stationed adjacent to the handwheels 42, 62, can control the complete operations of opening andclosing the carrier as required, tilting the walking beam and swingingthe jib 15. The lever by a proper proportion of its longer and shorterarms, gives the necessary power for raising the walking beam, and theprovision of the lever 37 enables the cable 24 to accommodate itself tothe rocking movement of the walking beam.

The lever 37 is counter-balanced by a weight 89, (Fig. I), hung on acable 90 connected with said lever as at 91 and running over a sheave 92on the post 84.

Having thus described my invention I claim as new and desire to secureby Letters Patent:

1. In a loader of the class described, a grapple comprising a series ofgrabs pivoted between their ends to rock in a vertical plane andprovided at their lower ends with tines, the respective tines beingdisposed toward one another, a cable having connections with the severalgrabs above the pivots thereof, to suspend the grapple and serve to openthe grabs, a second cable to close the grabs, and branch cablesconnected with the second cable and each having running engagement withthe grabs below the pivots thereof and made fast to a relatively fixedpart of the grapple. V

2. In a loader, a frame, a series of grabs pivotally hung between theirends on said frame, a cable connected with the several grabs above thepivots thereof to close the grabs, a second cable, a ring suspended onthe second cable, and flexible elements each connected at one end withthe ring, and made fast at their opposite ends to said frame, saidflexible elements having running engagement with the grabs below thepivots thereof.
